[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides an edible oil pressing and filtering device, such as Figure 1 and Figure 4 As shown, it includes a workbench 1, an oil pressing component, a filter component and a scraper 7. The upper end of the workbench 1 is provided with an oil pressing component that can squeeze the oil cake for oil extraction. Both sides of the workbench 1 are fixed with enclosures 15. The sides of the enclosures 15 are penetrated with a placement groove. The filter component is arranged at the lower end of the oil pressing component. The filter component includes a filter plate 3. The filter plate 3 is slidably connected to the placement groove of the enclosure 15. Figure 5 As shown, a filter screen 31 is provided at the center of the filter plate 3, and limiting grooves 32 are provided on both sides of the filter plate 3. A notch 18 is provided on the side of the workbench 1 at the lower end of the filter plate 3. Figure 7 and Figure 8As shown, short shafts 5 are fixedly connected to the inner bottom corners of the vertical plates at both ends of the workbench 1, a limiting shaft 6 is provided on one side of the short shaft 5, a scraper 7 is provided between the two short shafts 5, and a rotating drum 71 is fixed at both ends of the scraper 7. The scraper 7 is rotatably connected to the short shaft 5 through the rotating drum 71. An arc groove 72 is opened through the side of the rotating drum 71, and the limiting shaft 6 is slidably connected in the arc groove 72. The scraper 7 is in an inclined state, and the free end of the scraper 7 keeps in contact with the filter plate 3. The grease produced by squeezing the oil cake by the oil pressing assembly drips onto the filter screen 31 of the filter plate 3 below. The grease is filtered by the filter screen 31, and the residual impurities in the grease remain on the filter screen 31. As the amount of grease filtered increases, the amount of residual impurities accumulated on the filter screen 31 increases, which will lead to a decrease in filtration efficiency. The accumulation of residue may also become a breeding ground for bacteria and mold, affecting food safety. The filter plate 3 is pulled out of the mounting groove from the notch 18. As the filter plate 3 is pulled out, the residue on the filter plate 3 will be scraped off by the scraper 7. The scraped and cleaned filter plate 3 is pushed back into the mounting groove to filter the grease. The scraper 7 is in contact with the filter plate 3 by gravity and is tilted. At this time, the limit shaft 6 is located at the rightmost end of the arc groove 72. During the process of pulling out the filter plate 3, the scraper 7 will be pulled at the same time, so that the drum 71 should rotate counterclockwise around the short axis 5. However, due to the limiting effect of the limit shaft 6 on the scraper 7, the scraper 7 cannot rotate, which hinders the pulling out of the filter plate 3, thereby achieving the scraping effect. During the process of pushing the filter plate 3 back, the scraper 7 will be pushed, so that the drum 71 rotates clockwise around the short axis 5, and the limit shaft 6 will slide along the arc groove 72. The limit shaft 6 no longer restricts the rotation of the scraper 7, and the scraper 7 will not hinder the pushing back of the filter plate 3, so that the filter plate 3 can be easily pushed back.

[0030] like Figure 6 As shown, the oil pressure assembly includes a clamping member and a hydraulic pump 2. The clamping member is arranged inside the workbench 1 and includes an adjustable clamping column 13 and a fixed clamping column 14. Figure 2 and Figure 7As shown, a slide groove 11 is provided on the side surface of the vertical plates at both ends of the workbench 1, and a threaded rod 12 is slidably connected inside the slide groove 11, and the threaded rod 12 passes through the two slide grooves 11, and an adjustable clamping column 13 is fixed on the side surface of the threaded rod 12, and multiple fixed clamping columns 14 are fixed on the inner side of the vertical plates at both ends of the workbench 1, and the hydraulic pump 2 is fixed on the side surface of the vertical plate at one end of the workbench 1, and the slide groove 11 is arc-shaped, and the slide groove 11 is located at the upper end of the output shaft of the hydraulic pump 2, the adjustable clamping column 13 and multiple fixed clamping columns 14 are arranged circumferentially around the output shaft of the hydraulic pump 2, and the output shaft of the hydraulic pump 2 is fixedly connected to a pressure plate 21, and a receiving platform 22 is provided opposite the pressure plate 21, and the receiving platform 22 is fixed on the vertical plate of the workbench 1, and a plurality of protrusions are provided on the end face of the receiving platform 22. Loosen the fixing nut on the threaded rod 12 to move the adjustable clamping column 13 along the slide groove 11 in the opposite direction away from the output shaft of the hydraulic pump 2, and stack multiple oil cakes to be squeezed between multiple fixed clamping columns 14 along the length direction of the fixed clamping column 14 to reset the adjustable clamping column 13. Tighten the fixing nut on the threaded rod 12. The adjustable clamping column 13 and multiple fixed clamping columns 14 limit the oil cakes to prevent them from slipping out of the device when they are squeezed. Start the hydraulic pump 2 to push the pressure plate 21 to move and squeeze the oil cakes. Under the squeezing of the pressure plate 21 and the receiving platform 22, the grease in the stacked multiple oil cakes seeps out.

[0031] like Figure 3 and Figure 5 As shown, the filter assembly also includes a slide post 4, and both ends of one side of the workbench 1 are fixedly connected to ear frames 16. A through hole 17 is provided on the side of the workbench 1 corresponding to the ear frame 16. The through hole 17 is connected to the placement groove of the enclosure 15. The slide post 4 is slidably connected to the inside of the ear frame 16, and a baffle 41 is fixedly connected to the peripheral side of the slide post 4. A spring 42 is provided between the baffle 41 and the ear frame 16. The spring 42 is sleeved on the slide post 4, and the end of the slide post 4 is slidably connected to the through hole 17, and the end of the slide post 4 is in contact with the filter plate 3. When the filter plate 3 needs to be pushed back, the slide post 4 is pulled out from the limiting groove 32 by pulling it out of the limiting groove 32, thereby canceling the restrictive effect of the slide posts 4 on the filter plate 3, so that the filter plate 3 can be pushed back into the positioning groove.

[0032] like Figure 1 and Figure 9As shown, an oil hopper 8 is provided at the lower end of the filter plate 3. This hopper 8 is slidably connected to the workbench 1. An oil outlet 81 is provided at the center of the hopper 8. A slideway 82 is provided below the outlet 81. This slideway 82 is fixed to the hopper 8, with its free end tilted downward. Grease filtered by the filter 31 drips onto the hopper 8, where it is collected and flows through the outlet 81 onto the slideway 82. A container can be placed at the outlet of the slideway 82 to collect the grease. After a period of time, the hopper 8 can be removed for cleaning.

[0033] like Figure 1 and Figure 7 As shown, a storage cabinet 9 is provided at the lower end of the scraper 7, and a slag collecting bucket 91 is slidably connected to the interior of the storage cabinet 9. The residue impurities on the filter screen 31 are scraped off by the scraper 7 and fall into the slag collecting bucket 91. The slag collecting bucket 91 can be pulled out of the storage cabinet 9 to remove the residue impurities.

[0034] Adopting this utility model, such as Figure 1 and Figure 2As shown, loosen the fixing nut on the threaded rod 12, and the adjustable clamping column 13 moves along the slide groove 11 in the opposite direction away from the output shaft of the hydraulic pump 2, and multiple oil cakes to be squeezed are stacked and placed between the multiple fixed clamping columns 14 along the length direction of the fixed clamping column 14, so that the adjustable clamping column 13 is reset. The adjustable clamping column 13 and the multiple fixed clamping columns 14 limit the oil cakes to prevent them from slipping out of the device when the oil cakes are squeezed. Start the hydraulic pump 2 to push the pressing plate 21 to move and squeeze the oil cakes. Under the squeezing of the pressing plate 21 and the receiving platform 22, the grease in the stacked multiple oil cakes seeps out and drips onto the filter screen 31 of the filter plate 3 below. The grease is filtered by the filter screen 31, and the residual impurities in the grease remain on the filter screen 31. The grease filtered by the filter screen 31 drips onto the oil collecting hopper 8, which is collected by the oil collecting hopper 8 and flows out through the oil outlet 81 to the slide 82. A container is placed at the outlet of the slide 82 to collect the grease. As the amount of grease filtered increases, the amount of residue and impurities accumulated on the filter screen 31 increases, which will lead to a decrease in filtration efficiency. The filter plate 3 is pulled out of the placement groove from the notch 18. As the filter plate 3 is pulled out, the residue on the filter plate 3 will be scraped off by the scraper 7. The scraped residue and impurities will fall into the slag collecting bucket 91. The slag collecting bucket 91 can be pulled out of the storage cabinet 9 to remove the residue and impurities. The end of the slide column 4 is always in contact with the side of the filter plate 3 under the elastic action of the spring 42. When the filter plate 3 is completely built into the placement groove, The spring 42 is in a compressed state. As the filter plate 3 is pulled out, when the end of the slide post 4 enters the limit groove 32, under the elastic action of the spring 42, the spring 42 is reset and is no longer in a compressed state. The slide posts 4 on both sides will clamp and restrict the filter plate 3 to prevent the filter plate 3 from being completely pulled out of the installation groove. Pulling the slide post 4 outward to pull it out of the limit groove 32 can cancel the restrictive effect of the slide posts 4 on both sides on the filter plate 3, and the filter plate 3 that has been scraped and cleaned can be pushed back into the installation groove to filter the grease.

[0035] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
